The correlation coefficient that represents a moderate negative correlation is r = -0.64
Which value corresponds to a moderate negative correlation?
For negative correlations, we can define intervals based on the "strength" of the correlation.
- By definition, from [-1, -0.7] we have a strong negative correlation.
- From [-0.7, -0.3] we have a moderate negative correlation.
- From -0.3 onwards, we have a weak negative correlation.
Then we need to find values of r such that:
-0.7 < r < -0.3
We can see that the only value on that interval is r = -0.64, so that is the correct option.
